VEHICLE-Basics.

To all whom it may concerit':l

Be it knownthat I, BARTHOLOMEW VIOLA, a citizen of the United States,residing inborough oiBrooklyn,

in thecounty of AKingsandStatel of New York, have invented certain newand useful Improvements .in Vehicle-Brakes, of Iwhich the following is aspecifica- This invention has reference to devices for arresting themovement of vehicle wheels, wherein the stopping of the vehicle iscaused' by a brake arrangement oper- One of the objects of the inventionis toprovide an improved 'form of 4brake device whereby two of the pliedthereto for the purpose of slightly retarding the vehicle,` or can havea very strong pressure applied Specification of Lettera-Iatent.Applicaties'sisasngmso.190e. sam No. esattal Patented Sept. 1?,v 1907.

moving the cone clutch members into and out of engagementwith theirrespective clutch members. To do this, the cones are/simultaneouslyshifted on the axle toward and from each other. In 4the construct-ionillustrated, this is accomplished `by a single lever or operatingmember., Means are also provided whereby the pressure or tension on thecone members is equally effected in 4opposite directions to apply ythebrakes. As illustrated, the cone members are each operated by a lever,which levers are connected at one end by a 7,0 link, while the otherends ofthe levels are4 moved toward and from each other.. A lever 21 hasa ring por whereby the rotation of the wheels will be very rap: `tion 22surrounding the cone member 15 and pins 23 in idly and efiicientlyarrested and held in such position against further movement.Y

.A further object of the invention isto provide a brake device that willbe equally operative on both wheels; anc-1 which will have a wedgevaction retaining the brake in locked position. l

In the accompanying drawings presenting one embodiment of my invention,Figure 1 is a bottom plan view of the device'applied to the running gearofa vehicle, in the nature oi a motor vehicle. Fig.s 2`is a vertionewheel. Fig. 4 is a side elevation, partly in section of one of. theclutch members. Fig. 5 is 'an end eleva-` side elevation of the vehicleon a reduced scale. A y The lorakedevicev is shown applied on therearaxle 9 that carries wheels l0 and 11, the axle supporting a frameWork denoted generally byl2. For each of the into and 4out ofengagement, but prevented from rotating. The wheel l0 is provided with`a clutch member 13 secured thereto, having aconical opening 14, intowhich slides a cone clutch member 15 'that is rotatably mounted ontheaxle 9. The cone l5 may be provided with a suitable face memberl toinsure its frictional engagement with' theother clutch m'ember. Asshown, a number oi taperedwooden blocks 17, having inclined ordove-tailed sides, slide intogdove formed by means -of ribs 18 on thecone whose opposite sides are undercut or' beveled as-shown, convergingoutwardly. Upon these wooden blocks being slipped into position anddriven home, they will be very tightly engaged between the ribs'andsecurely locked. in position against' rotation by their frictionalengagement with the wheel cone member. A similar clutch member'isprovided for the wheel 11 comprisinga the cone member extendintoopenings 24 inthe ring Aplever 25 is similarly connected with the cone'mem 75 ber 19 on the oppositeside, by pins 26 `engaging openi ings 27 inthe lever. At their rear end, the levers are pivotally connected bya'link28, whosezpivotal points can be adjusted by means oi a turn-buckle29 to and from each other. At the front end lever 21 is pivotally 80connected with a nut member 30 that engages a threaded' portion 3l of ashaft 32. At itsforwardend, lever 25 is pivoted to a nut member 33engagfnig the threadedportion 34 of the shaft 82 but the latter nut andthread are oppositely. formed, that is, the two threaded-portions-oi theshaftare right andY left handed, therefore uponwrocking the shaft in`one direction, `the nuts 30 and 33 will be moved toward each other, andwill be caused to recede upon moving the shaft in the oppositedirection. Any desired mean's may be employed to rock the shaft 32. 90As illustrated, the shaft is shown as providedwitha crank 35 that i'soperated by a lever 3,6 through a c0n necting rod 37 pivoted to thecrank and lever'.

i From the described construction, it will be seen that when the lever 36 is moved backward, `the rocking ,of 95 the shaft will cause the twonuts to move outwardly and shiit the brake levers in the same direction.But

the other ends of the levers being connected by a rigid link, will beprevented from movement, therefore the levers will act as if pivoted attheir rear to a stationary fulcrum which will cause theconestomoveoutwardly towards each of the clutch members on the1 wheels;l thereby causing engagement of the brake members. Obviously theswinging of the lever 36 in the opposite direction will move the nutmembers inward and shift i the cones away from their respectiveV clutchmembers, releasing the brake. The degree of pressure applied on theclutch members can be easily regulatedby' the 4amount of movement givento the opera-ting lever. Furthermore, the equal engagement of the twoclutch members will be insured by reason of the link 28, permitting themovement of the Afulcrum points of the le-` Suitable means areprovidedfor simultanedusly 60 i vers by reaction, se that. nn equalpressure will be ap plied en the two clutch members. Te compensate ierweer on the (finti-h tunes, the tnxbbuekle 2Q can be adjusted. Anfl :isille'wemlen iure blecks oi the eene members oi' the clutch become wornaway, they can be readily replaced by simply driving tbemeui. andinserting new ones.

li desired, the weight oi the levers operating the Clutch members can beenrriecl from the frame, by means et brackets 35 secured io the frame at3i), and extending flown tenuti eonneeted with the levers 2l and 25 :ittheir rear portions.'
